Details

The TOA TeachIR IR-802 SET wireless microphone classroom sound system is simple to install, superb quality & interference-free.

An infrared voice transmission system ensures that all pupils can hear the teacher clearly across the whole classroom, regardless of high ambient noise. When children can hear clearly, concentration levels can be more easily maintained and the teacher is protected from vocal strain and fatigue.

The TOA IR802 SET infrared classroom sound system consists of one central wide dispersion loudspeaker connected via CAT5 cable to the tuner. A handheld wireless microphone with rechargeable batteries and dual charger are also included. 

The TeachIR IR-802 SET comprises of the IR-802T tuner, IR-820SP amplified loudspeaker, one IR-200M hand held wireless microphone, IR-200BT-2 rechargeable batteries & a IR-200BC two way battery charger.

The IR-802T  infra red wireless tuner has a built in pre amp and offers 3 auxiliary inputs for additional sound sources such as a PC, TV/DVD player or MP3 player.

• 3 AUX inputs for PC, TV/DVD player and MP3 audio player
• Output muting by 25V speaker line signal from emergency / intercom paging
• Equalizer control knobs for low-, mid- and high-frequency outputs
• Mixing output terminal for ALD (Assistive Listening Device)
• Frequency response optimized to reduce acoustic feedback in 100 m² classrooms

The IR-820SP is a wide dispersion ceiling mounted loudspeaker providing coverage up to 100m². It has a built-in infra red receiver and 20 watt digital amplifier. The bass reflex design achieves a wide frequency response and gives an even sound coverage over a wide radius. It is connected to the tuner by CAT5 cable.

The IR-200M is a lightweight, wireless hand held electret condenser microphone with dual infra red transmitters built in.

The IR-200BC quick charger is capable of charging up to 2 microphones (both hand-held and beltpack types) at a time. With the rapid charging feature, up to 2 infrared microphones can be simultaneously charged in 3 hours (maximum).
